The United States experienced a significant decline in international immigration that affected population growth across metropolitan areas nationwide, according to newly released census data.

From June 2023 to July 2024, the number of new residents who were international immigrants dropped by 70 percent compared to the previous year period. This dramatic reduction in immigration had widespread effects on population dynamics across the country.

Large urban counties and border regions saw the most pronounced impact from the immigration slowdown. New York City's population remained essentially flat during this period, marking a notable change from previous growth patterns driven by international migration.

The immigration decline contributed to broader population trends across the United States, with three-quarters of U.S. counties experiencing either slowed population growth or negative growth during the measurement period.

The census data highlights how international migration patterns significantly influence demographic changes in American communities, particularly in major metropolitan areas that have historically relied on immigration for population growth and economic vitality.
